I'm trying to configure a Drupal installation on IIS 7.5 (Windows 2008R2). I installed PHP via the Web Platform Installer, and I do have Drupal running.
However, when I enable CSS Aggregation via admin/settings/performance, the aggregated css files are not being generated. I get the following error:
The selected file could not be copied, because no file by that name exists. Please check that you supplied the correct filename.
When I browse down to sites/files, I do see a css directory created. I have even gone so far as to add the "Everyone" group to this directory and give it Modify privileges. However, this does not make any difference.
I also tested out the PHP temp directory to make sure that is writable. I can get imagecache working properly.
Has anyone else seen these errors? Does anyone have any suggestions? I'd really like to get this working under IIS if possible.
Thanks!

Fixed it!
Sure enough as I took the time to post this, I fixed it. Blah.
The solution is to set the file system temp path on "admin/settings/file-system" to the same directory that the PHP "upload_tmp_dir" variable is pointed to.
